ABSTRACT The kinematics of the joint and the contact mechanics are considered while designing the tibial insert used in total knee arthroplasty (TKA). The computational contact analysis is an appropriate method for assessing the damage accumulated in the knee joint as a result of the dynamic motion that it undergoes. The experimental system is extremely costly, making any changes to the prosthetic elements challenging. The knee joint prostheses in this study are modeled using the modeling software CATIA V5 (Computer Aided Three-dimensional Interactive Application). This software is used to simulate the knee joint. When rapid flexion is applied, the femoral and tibial parts have been developed with two curves that mix to maximize the braking effect. ABAQUS/CAE 6.14 is used to carry out a 3D finite element analysis, followed by a finite element technique analysis. The tibial insert design uses two biomaterials suited for the job: UHMWPE and contemporary stabilized UHMWPE. The mechanical characteristics of these materials are exceptionally high. The contact analyses have been applied to calculate the damage rate on the tibial insert while considering the effect of wear. Both the traditional Archard law and the modified Archard law have been utilized in calculating linear wear. In addition, compared to UHMWPE, the material stabilized with UHMWPE demonstrates improved resistance to linear surface failure (depth). Keywords: Wear rate; finite element method; CATIA; ABAQUS
